Struct mysql_async::binlog::events::QueryEvent

pub struct QueryEvent<'a> { /* private fields */ }

A query event is created for each query that modifies the database, unless the query is logged row-based.

Implementations

impl<'a> QueryEvent<'a>

pub fn new( status_vars: impl Into<Cow<'a, [u8]>>, schema: impl Into<Cow<'a, [u8]>> ) -> QueryEvent<'a>

Creates a new instance.

pub fn with_thread_id(self, thread_id: u32) -> QueryEvent<'a>

Sets the thread_id value.

pub fn with_execution_time(self, execution_time: u32) -> QueryEvent<'a>

Sets the execution_time value.

pub fn with_error_code(self, error_code: u16) -> QueryEvent<'a>

Sets the error_code value.

pub fn with_status_vars( self, status_vars: impl Into<Cow<'a, [u8]>> ) -> QueryEvent<'a>

Sets the status_vars value (max length is `u16::MAX).

pub fn with_schema(self, schema: impl Into<Cow<'a, [u8]>>) -> QueryEvent<'a>

Sets the schema value (max length is `u8::MAX).

pub fn with_query(self, query: impl Into<Cow<'a, [u8]>>) -> QueryEvent<'a>

Sets the query value.

pub fn thread_id(&self) -> u32

Returns the thread_id value.

thread_id is the ID of the thread that issued this statement. It is needed for temporary tables.

pub fn execution_time(&self) -> u32

Returns the execution_time value.

execution_time is the time from when the query started to when it was logged in the binlog, in seconds.

pub fn error_code(&self) -> u16

Returns the error_code value.

error_code is the error code generated by the master. If the master fails, the slave will fail with the same error code.

pub fn status_vars_raw(&'a self) -> &'a [u8]

Returns the status_vars value.

status_vars contains zero or more status variables. Each status variable consists of one byte identifying the variable stored, followed by the value of the variable.

pub fn status_vars(&'a self) -> &'a StatusVars<'a>

Returns an iterator over status variables.

pub fn schema_raw(&'a self) -> &'a [u8]

Returns the schema value.

schema is schema name.

pub fn schema(&'a self) -> Cow<'a, str>

Returns the schema value as a string (lossy converted).

pub fn query_raw(&'a self) -> &'a [u8]

Returns the query value.

query is the corresponding LOAD DATA INFILE statement.

pub fn query(&'a self) -> Cow<'a, str>

Returns the query value as a string (lossy converted).

pub fn into_owned(self) -> QueryEvent<'static>

Trait Implementations

impl<'a> BinlogEvent<'a> for QueryEvent<'a>

const EVENT_TYPE: EventType = EventType::QUERY_EVENT

An event type, associated with this struct (if any).

impl<'a> BinlogStruct<'a> for QueryEvent<'a>

fn len(&self, _version: BinlogVersion) -> usize

Returns serialized length of this struct in bytes.

impl<'a> Clone for QueryEvent<'a>

fn clone(&self) -> QueryEvent<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for QueryEvent<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> Hash for QueryEvent<'a>

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'de> MyDeserialize<'de> for QueryEvent<'de>

const SIZE: Option<usize> = None

Size hint of a serialized value (in bytes), if it’s constant.

type Ctx = BinlogCtx<'de>

Some structs defines deserialization in the context of another value.

fn deserialize( ctx: <QueryEvent<'de> as MyDeserialize<'de>>::Ctx, buf: &mut ParseBuf<'de> ) -> Result<QueryEvent<'de>, Error>

Deserializes self from the given buf.

impl MySerialize for QueryEvent<'_>

fn serialize(&self, buf: &mut Vec<u8>)

Serializes self into the buf.

impl<'a> PartialEq for QueryEvent<'a>

fn eq(&self, other: &QueryEvent<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
